"I kind of looked over and saw what I thought was somebody asleep at the wheel and I was like that can’t be right, so I did a double take, looked over and sure enough this guy was just, head between his legs completely asleep,” Randall, a local sports journalist, told NBC10 Boston. "It seemed like he had his cruise control on around like 55-60 miles per hour."

Randall sat stunned before pulling out his phone to record. He tried honking to wake the driver and passenger up but says "it didn't work at all."

"I'm never going to look at one the same," he said. "I'm always going to look to see if somebody's asleep."

The Tesla Autopilot feature is designed to actively guide cars from on-ramp to off-ramp, including suggesting and making lane changes, navigating highway interchanges, and taking exits. However, Tesla says on its website that the feature is intended for use with a fully attentive driver, who has their hands on the wheel and is prepared to take over at any time.

"Many of these videos appear to be dangerous pranks or hoaxes," Tesla said Monday night in a statement. "Our driver-monitoring system repeatedly reminds drivers to remain engaged and prohibits the use of Autopilot when warnings are ignored. At highway speeds, drivers typically receive warnings every 30 seconds or less if their hands aren't detected on the wheel.

"Tesla owners have driven billions of miles using Autopilot, and data from our quarterly Vehicle Safety Report indicates that drivers using Autopilot experience fewer accidents than those operating without assistance."

Randall did not contact police after taking the video. State police first told NBC10 Boston they were aware of the incident from media reports but were not contacted by anyone nor were they sent the video.

State police later said that they reached out to Randall on Monday, but he was unable to provide a license plate or any other identifying information about the vehicle or driver. No further investigative steps were being taken, they said.
